Abstract (en)

[origin: EP0397439A2] A vinyl chloride resin for safety glass, comprising either particles of a copolymer of a vinyl chloride monomer and an epoxy-containing monomer, having a particle diameter up to 5 mu m and a greater epoxy content in an outer shell than in a core of the particles, or agglomerates of the particles, and process for the preparation of this resin, comprising either adding an epoxy-containing monomer into a polymerization reaction mixture of a vinyl chloride monomer substantially during a latter half of the polymerization reaction of the polymerization mixture or adding an epoxy-containing monomer and a vinyl chloride monomer either in the form of a mixture solution or separately but at the same time into a polymerization mixture of the vinyl chloride monomer.
